Tool Table
The "Tool Table" is a text file that contains information about each tool. The file is located in the
same directory as your configuration and is called "tool.tbl". The tools might be in a tool changer or
just changed manually. The file can be edited with a text editor or be updated using G10 L1. See
the Lathe Specifics Section for lathe tool table example. The maximum number of entries in the tool
table is 56. The maximum tool and pocket number is 99999.

In general new tool table line format is:
• T - integer tool number
• P - integer pocket number
• D - float tool diameter
• X..W - float tool length offset on specified axis
• I - float front angle (lathe tools)
• J - float back angle (lathe tools)
• Q - int tool orientation (lathe)

Tool Changers
EMC supports three types of tool changers "manual", "random location" and "fixed location". Information about configuring an EMC tool changer is in the Integrators Manual.
Manual Tool Changer
Manual tool changer (you change the tool by hand) is treated like a fixed location tool changer and
the P number is ignored. Using the manual tool changer only makes sense if you have tool holders
that remain with the tool (Cat, NMTB, Kwik Switch etc.) when changed thus preserving the location
of the tool to the spindle. Machines with R-8 or router collet type tool holders do not preserve the
location of the tool and the manual tool changer should not be used.
Fixed Location Tool Changers
Fixed location tool changers like lathe turrets the tools are in a fixed position in the tool changer.
When EMC is configured for a fixed location tool changer the "P" number is ignored (but read,
preserved and rewritten) by EMC, so you can use P for any bookkeeping number you want.
Random Location Tool Changers
Random location tool changers swaps the tool in the spindle with the one in the changer. This type
of tool changer the tool location will always be in a different pocket after a tool change. When a
tool is changed EMC rewrites the pocket number to keep track of where the tool are. T can be any
number but P must be a number that makes sense for the machine.
